Abstract: The differences in the hysteresis loops of the (DyPr)CoFeB ferrimagnetic alloy powders dispersed in a polymer and eicosane, in a free form, and in sintered samples, have been analyzed. It has been shown that the differences are determined by changes in the dipole–dipole interaction between microparticles upon their dissolution, as well as are determined by the mechanical rotation of the particles and the degree of pinning of their easy axes.
